System clock.
System clock represents the system-wide real time wall clock.
It may not be monotonic: on most systems, the system time can be adjusted at any moment. It is the only clock that has the ability to be displayed and converted to/from UNIX timestamp.
To get the current time:
system_clock::TimePoint now = system_clock::now();
To convert a TimePoint to/from UNIX timestamp:
system_clock::TimePoint time = ...; uint64_t timestampInMilliseconds = toUnixTimestamp(time).count(); system_clock::TimePoint time2 = fromUnixTimestamp(milliseconds(timestampInMilliseconds));
